RELATED APPLICATION DATA

This application is a continuation of U.S. application Ser. No.10/899,699 filed Jul. 26, 2004.

FIELD OF THE INVENTION

The present invention relates to gaming machines and methods of playinggames.

BACKGROUND OF THE INVENTION

Gaming continues to grow in popularity and is spreading geographicallyand demographically. As gaming grows, so does the player's desire fornew and exciting games.

A variety of games have been developed recently which include newfeatures designed to add excitement to the game play. These games andgaming machines suffer from a number of drawbacks.

First, a number of games presently offer “bonus” events. These events,however, are generally very static events which are not very exciting.For example, in the play of some slot-type games, if the player receivesa certain combination of symbols, a circular wheel printed with bonusvalues may spin and stop, yielding the player with a bonus pay. Thesetypes of bonus events have become common-place, and do not include anyplayer participation.

Second, most machine-presented casino games suffer from the problem thatthey are single player games. Thus, some players like to play games suchas poker and bingo where multiple players are involved. Otherwise, whenplaying a gaming machine, the game play experience is very isolated.

The present invention is a gaming machine, system and method of gameplay which has numerous advantages over the prior art games and gamingdevices.

SUMMARY OF THE INVENTION

The invention comprises methods of playing/presenting one or more games,gaming machines for presenting games, and gaming systems includinggaming machines. Preferably, the games are played as wager type games,with the opportunity for monetary awards for winning results.

One embodiment of the invention is a method of presenting and playing agame. The game includes at least one base or main game event. The basegame is presented to a player, and the outcome of the base game isdetermined. If the outcome of the base game is a bonus event initiatingoutcome, then a bonus event is initiated. The bonus event initiatingoutcome may comprise a particular symbol or combination of symbolsreceived while playing the base game.

If the bonus event is initiated, a bonus event period of time isdetermined. That period of time may be randomly determined or determinedbased upon one or more criteria. The bonus event is initiated and abonus game is presented to a player. The outcome of the bonus game isdetermined. If the bonus event time period has not yet expired, additionbonus games are presented. Once the bonus event time period expires, thebonus event is terminated.

In one embodiment, credits, points or the like are awarded for winningoutcomes of the bonus game. The credits or points are aggregated duringthe bonus event and are awarded to the player for play of the event.

Preferably, the bonus event time period is displayed. In one embodiment,a timer is displayed which indicates the time remaining in the bonusevent until its termination.

Various bonus games may be presented, and the bonus games played duringa single bonus event may vary. For example, the bonus game may comprisea slot-type game.

In accordance with this aspect of the invention, a player is presentedwith an opportunity to play as many bonus games as possible during aperiod of time defining a bonus event. The player attempts to win asmany bonus games as possible to achieve maximum bonus event winnings.The time nature of the bonus event increases the excitement of gameplay.

Further objects, features, and advantages of the present invention overthe prior art will become apparent from the detailed description of thedrawings which follows, when considered with the attached figures.

The gaming machine 20 illustrated and described is just one embodimentof a device which may be used to present a game in accordance with theinvention. Other devices may be utilized. For example, the gamingmachine 20 may also comprise a computing device, such as a laptop ordesktop computer. Game information may be transmitted via acommunication link to a remote player. The communication link mayinclude, for example, the Internet. The game information may be utilizedby the remote player's computer, such as by displaying game informationon an associated screen. A player may provide input via a keyboard,mouse or other input device.

Various aspects of the games of the invention may be presented at otherthan a gaming machine. For example, as described below, various featuresof the invention may be implemented in conjunction with a table game.

Preferably, the gaming machine 20 is configured to establish atelecommunication link to the player of the game and/or from the playerat the gaming machine to a remote location. In one embodiment, atelecommunication link may be established directly to the gaming machine20 from a remote location, such as a telephone exchange, in similarfashion to a telephone in a home. Referring to FIG. 2, in oneembodiment, a plurality of gaming machines 20 are all associated withone or more common devices.

In one embodiment, a telecommunication link exists between the gamingmachine 20 and a central location, such as server 48. The gamingmachines 20 and server 48 may comprise a gaming system 50, such asoperated by a casino.

The server 50 may have a variety of configurations and may comprise asingle device or a group of devices. In one embodiment, the server 50comprises a computing device including a processor, a memory for storingdata, and at least one transceiver. The transceiver comprises acommunication interface for accepting information from, or transmittinginformation to, the various gaming machines 20.

In one embodiment, the server 50 acts as a telecommunication controller,routing calls from remote locations to appropriate machines 20, orrouting calls from machines 20 to outbound destinations. For example, inone embodiment, a phone number (or other unique identifier) is assignedto each gaming machine 20. Callers may attempt to call a player of agaming machine 20 using the telephone number assigned to the machine 20.Such calls may be placed remotely and routed by the server 50 to theappropriate machine.

Similarly, calls may be routed through the server 50 to outboundlocations, such as a local exchange. For example, as illustrated, acommunication link 52 may be established between the gaming machine 20and a remote telephone 54 via a wired telecommunication link. Inaddition, a link may be established with a wireless telephone 56, suchas via one or more cellular, satellite or other links 58.

Of course, the server 50 (or other servers 50) may be configured toperform a variety of tasks. For example, the server 50 may store playerinformation and game play information, as known in the art of playertracking systems. In this regard, the server 50 may obtain informationfrom the gaming machines 20 to track game play. The server 50 may also,as indicated above, generate game content for use by the gaming machine20.

In one embodiment, a communication link is provided between each gamingmachine 20 and the server 50. The links may be dedicated or shared.Further, multiple links may be provided for different purposes. Forexample, one link may be utilized to transmit player tracking/game playinformation. Another link may be utilized for the telecommunications.Yet another link might be utilized to transmit game information, such aswhere the game is controlled by the server.

The various links between the gaming machines 20 and the server 50 maybe wired or wireless or combinations thereof. Communications may beeffected using a variety of hardware and software, and in accordancewith a number of standards, such as IEEE-1394, IEEE802.xx or the like.

One embodiment of a game of the invention will now be described withreference to FIG. 3. In a preferred embodiment, a game is presented as awagering game. In such a configuration, a player wagers value for theopportunity to be awarded winnings. Of course, the game, or at leastportions thereof, may be played for entertainment only, with the playernot require to wager value.

In the wager format, as illustrated, in a step S1 the player places, andthe gaming machine accepts, a wager. As described above, if the wager isin the form of monetary value, the wager may be placed in a variety offashions. In one embodiment, a player inputs currency, coins or a mediumrepresenting or associated with such value, such as a coded ticket,credit/debit card or the like. The value may be credit to the machine20, the player then placing a wager specifically for a game using the“bet” button 30. In that case, the number of credits belonging to theplayer is reduced by the amount of the bet.

In response to the wager, the game is then presented. In one embodiment,this step comprises the gaming machine 20 presenting a base game. In oneembodiment, this game comprises the random selection of indicia, one ormore of which, alone or in combination, comprise winning or losing gameresults. In the case of the gaming machine 20 described above, the basegame comprises the rotation of the reels 24 a,b,c to a stopped positionin which they display a set of symbols or indicia. This set of indiciarepresents the outcome of the base game.

In one embodiment, if the indicia which appear in specific locations,such as along a payline 60, comprise a winning indicia or winningcombination of indicia, then in a winning outcome is declared. Asindicated below, there may be a number of winning combinations, one ormore of which trigger different outcomes or results.

In the embodiment illustrated, the game is presented on three reels 24a,b,c, each configured to display at least three symbols. There may beas few as one or multiple paylines. In the configuration illustrated,five paylines are illustrated.

In one configuration, the number of paylines which are activated isdependent upon the size of the player's wager. For example, if theplayer places a wager of a single amount, such as a single coin orcredit, then a single payline may be activated. In that instance, onlyindicia appearing along that single payline are considered indetermining the outcome of the game. Additional coins or credits wageredmay activate additional paylines. A maximum bet, such as five coins orcredits, may activate all of the paylines.

In one embodiment, symbols on reels are selected from one or more of thefollowing: TABLE 1 A. Dialing For Dollars logo B. Dialing For Dollars“Bonus Round” symbol C. Slot-A-Thon logo D. Slot Machine with TV typeantennae coming out of the top E. Cellular phone F. Old style phone G.Modern phone H. Telephone variation #4 I. Telephone variation #5 J.Address Book K. Telephone Book L. Stop watch symbol M. “Make A Call”icon N. Phone booth or pay phone O. 911 symbol P. Operator Q. Phone cardicon R. Prank call icon S. Can and a string symbol T. Wild symbol U.Multiplier type symbols V. Phone friends W. Slot-A-Thon bonus symbol X.Qualifier question symbol

Preferably, of course, the symbol or symbols which comprise winning andlosing combinations are known before the game begins.

In a step S3, the outcome of the base game is determined. In oneembodiment, this comprises determining if the symbol or symbols alongone more paylines are winning or losing combinations. As describedabove, in one embodiment, the outcome of the base game is known when thegame is initiated, (such as by random generation of a number by thegaming controller (or a random number generator associated therewith),that number corresponding to a particular possible outcome), and beforethe reels are rotated or before they stop. In this configuration, theoutcome of the game is known even before the reels stop spinning, andactually, the stopping position of the reels is determined by the thenknown outcome of the game.

The game may have a number of outcomes. As described below, in oneembodiment, there are five possible outcomes. Of course, the game may beplayed with varying types and numbers of possible outcomes.

In one embodiment, it may be determined that the outcome is no winningsymbol or combination of symbols (such as along an active payline), asin a step S4. In such event, the game may end, as in step S5. In apreferred embodiment, if there is no winning combination, the playerloses their wager and they are paid no winnings.

In one embodiment, as in step S6, it may be determined that the outcomeof the game is a particular winning symbol or combination of symbolscomprising a base win. For example, one or more symbols or combinationsof symbols may comprise a winning result which entitles the player to awinning. In such event, as in step S7, the player may be awarded awinning. The winning may be awarded in a variety of ways and maycomprise a number of things.

In one embodiment, the winning comprises monetary value. The size of thewinning may depend upon the size of the player's wager and/or theprobable frequency of receiving the particular winning combinations,among other factors. In one embodiment, the winning is awarded to theplayer in the form of credits. The player may elect to “cash out” thosecredits from the machine, such as by requesting that a value ticket beprinted by the printer 39, or by dispensing coins to the coin tray 36,among other ways. After the player is paid their winnings, the gamepreferably ends at step S5.

In one embodiment, as in step S8, it may be determined that the outcomeof the game is a particular winning symbol or combination of symbolsentitling the player to additional game play. In a preferred embodiment,the additional game play is offered to the player without additionalwager.

Aspects of one embodiment of such a game are described in greater detailbelow in conjunction with FIG. 4. In one embodiment, as in step S9, theplayer is awarded the opportunity for a number of free game spins. Theoutcome of those games is determined and play continues until all of thefree spins and associated events are completed, as in step S10. Ofcourse, the result of those games may vary, and may include winningoutcomes for which the player is awarded winnings. The game then ends atstep S5.

In one embodiment, as in step S11, it may be determined that the outcomeof the game is a particular winning symbol or combination of symbolsentitling the play to play a participant game. Aspects of one embodimentof such a game are described in greater detail below in conjunction withFIG. 5. In one embodiment, as in step S12, the bonus game is initiated.In step S13, the outcome of that game is determined. The outcome may bea winning or losing outcome, and may include awarding the player and/orthird party participant winnings. In step S5, the game then ends.

In one embodiment, as in step S14, it may be determined that the outcomeof the game is a particular winning symbol or combination of symbolsentitling the player to play a bonus event. Aspects of one embodiment ofsuch a game are described in greater detail below in conjunction withFIG. 6. In one embodiment, as in a step S15, the bonus event isinitiated or presented. In step S16, the outcome of that event isdetermined. The outcome may be a winning or losing outcome, and mayinclude awarding the player winnings. In a step S5, the game then ends.

A free spin bonus in accordance with the invention will now be describedin conjunction with FIG. 4. As indicated above, such a bonus event maybe initiated based upon a player receiving a particular symbol orcombination of symbols, as in step S8 of the method of game playillustrated in FIG. 3.

In one embodiment, the free spin bonus offers the player the opportunityto win a number of free spins. The number of free spins awarded mayvary, and may be as few as zero, but is preferably at least one and morepreferably 5 to 25.

In one embodiment, this bonus event includes the step of determining thenumber of free spin games which the player is entitled to play, and thenpermitting the player to play those games. Referring to FIG. 4, in astep S100, a call is initiated to the player. In the case of the gamingmachine 20 illustrated in FIG. 1, this step preferably comprises callingthe player via the handset 40.

The call may be initiated in a variety of ways. In a preferredembodiment, the controller of the gaming machine initiates the call,causing the player to be notified of an incoming call. This may includedissemination of an audible “ring,” as is well known in the art oftelephones. This may also include the display of information to theplayer, such as the display of a telephone and text indicating theplayer has an incoming call (such as displayed on display 38 of thegaming machine 20).

The player is provided the opportunity to answer the phone/take thecall. In the configuration of the gaming machine 20 illustrated in FIG.1, the player may answer the call by lifting the handset 40.Alternatively, the player may answer the call by pressing the “answer”button 32. Of course, the ways the player may take the call/answer thephone may depend upon the configuration of the gaming machine.

In one embodiment, a value is determined by how and when the call isanswered. In one embodiment, in a step S101, the player may answer thecall. Preferably, the longer the player waits to answer the call, thegreater the value which is assigned. In a step S102, a multiplier valueis set to the number of rings before the player answered the call. Forexample, the controller of the gaming machine may cause a ring to begenerated at spaced intervals of 2 seconds. Once the player answers thecall, the rings stop, and a multiplier is assign a value equal to thenumber of rings which were presented before the player answered thecall. In other embodiments, the value could be a multiple of the numberof rings, or the like.

In a step S103, the machine may answer the call automatically. In oneembodiment, the gaming controller is configured to answer the call aftera period of time if the player has not answered the call. In a stepS104, in such event, a multiplier value is then generated or selected.The multiplier value may be selected randomly from a set of values.Preferably, the multiplier values which may be selected and assigned bythe machine are less than that which the player has an opportunity towin. In one embodiment, the machine assigns a fixed multiplier of 2 forevery event.

In this manner, the player must determine whether they wish to attemptto wait for additional rings in an attempt to obtain a highermultiplier, in light of the risk of the machine answering and assigninga lower multiplier. For example, a player who has waited three rings maybe entitled to a multiplier of 3. If the player waits for a fourth ringbefore answering, the player may either obtain the ring and then amultiplier of 4, or the machine may answer, causing the player'smultiplier to be reduced to 2.

Next, a number of free spins are awarded, in step S105. In oneembodiment, the gaming controller makes a selection of an outcome frompossible selections. That selection is then transmitted to the player.In a preferred embodiment, the transmission of the selection is in theform of the call to the player. Preferably, the selection is presentedin audible form to the player. Examples of possible calls and numbers offree spins assigned thereto are set forth below: TABLE 2 1. Wrongnumber - 5 free games 2. I'll be late for dinner - 10 free games 3. Yourmother - 10 free games plus 2× more multiplier 4. Best friend withgossip - 15 free games 5. Radio Station promotion - 5 free games 6.Prank call - 2 free games

Now, the player is preferably provided the opportunity to play thegames, as instep S106. As indicated, these games are preferablypresented to the player without a requirement of an additional wager. Ina preferred embodiment, the games which the player is allowed to playmay either comprise the base game, as described above, or may be anothergame, such as presented on the video display of the gaming machine orpresented by other reels or the like. For example, the player may bepermitted to play a video slot game presented on the display 38 of thegaming machine 20 illustrated in FIG. 1.

In a step S107, the outcomes of the one or more games are determined. Ifthe outcome of one or more of the games is a winning outcome, the playeris preferably awarded winnings. In a step S108, any winnings arepreferably multiplied by the multiplier value which was assigned orgenerated previously. For example, if in a free spin game the playerobtained a winning combination having a payout of 20 credits and theplayer had obtained a multiplier of 3, then the player would be entitledto 60 credits. In a step S109, those winnings are awarded to the player.

As will be appreciated, to keep the free spin games simple, it ispreferred that those games not involve bonus events themselves, butsimply define winning or losing events. In other embodiments, the gamemay be more complex, with the player provided the opportunity to playbonus and other events, including further opportunity for additionalfree spin games or the like.

In one embodiment, the multiplier value for the event may be posted tothe player. For example, in the embodiment illustrated in FIG. 1, amultiplier value of 6× is shown. The multiplier value may be displayedby a display of the machine 20 after it has been generated as part ofthe event. Likewise, the number of credits won by the player as part ofthe outcome of a game may be displayed. For example, if the playerreceived a winning result having a 9 credit win, as multiplied by themultiplier (6), the player would be entitled to 45 credits, asillustrated. Of course, a credit meter may show the total number ofcredits which belong to the player from their value input, andwins/losses from the play of all games, including the bonus spins.

A participant bonus event in accordance with the invention will now bedescribed in conjunction with FIG. 5. As indicated above, such a bonusevent may be initiated based upon a player receiving a particular symbolor combination of symbols, as in step S11 of the method of game playillustrated in FIG. 3.

As one example, in the case of the symbol sets described above as usedin the play of the base game, a set of any three “telephone” symbols onan active payline may initiate this bonus event. For reasons which willbe apparent below, one embodiment of a bonus event may be referred to as“phone-a-friend”.

Initiation of the event may be accompanied by a notification at thegaming machine. For example, lights and sounds, along with audible ortext information, may be presented to the player to make them aware thatthis bonus event has been triggered and to add excitement to the game,including excitement to passers-by and other players.

Preferably, this event offers the player the opportunity to play a gamewith another player or participant. In one embodiment, the game involvesthe calling of another participant or player.

In a step S200, a player inputs a player number. Preferably, this playernumber is used in the play of the bonus event. In the case of the gamingmachine 20 illustrated in FIG. 1, the numbers may be input into thekeypad 44. In one embodiment, the player number is a 5 digit number(e.g. 33554).

In a step S201, a call is initiated to a third party participant. Thiscall may be initiated in a variety of ways. In one embodiment, theplayer is permitted to input a telephone number of a person they wish tohave participate. For example, a person may input the phone number fortheir wife, mother, father, brother, sister, friend or the like. Thephone number may be input using the keypad 44 in response to a prompt tothe player to input the number.

In another embodiment, the call may be placed to a person identified ina player tracking system. A gaming operator may permit players toprovide identifying information, including their telephone number. Thisinformation may be used, in part, to track the player's game play andreward them with awards for their play. In accordance with thisembodiment, the information may be used to identify them as aparticipant in the bonus event. The player information, including thetelephone number information, may be stored at a server (such as server50 of the system illustrated in FIG. 2). When this bonus event isinitiated, the gaming machine may contact the server and request atelephone number from the database. A player/telephone number may berandomly selected from the database and then transmitted to the gamingmachine for initiating the call.

In yet another embodiment, a telephone number may be randomly generatedby the gaming machine, and that number may be dialed in an attempt toform a link with a participant.

In one embodiment, a player may be permitted to select the way the callis placed (by input of a number of their choice, selection fromidentified participants in the database, or by random selection). Inanother embodiment, the manner by which the call is placed may randomlyselected, and thus change from game to game.

In these embodiments, the telephone number is preferably utilized in anattempt to form a communication link with a participant. In the case ofthe system illustrated in FIG. 2, the call may be placed from the gamingmachine 20 to another telecommunication device, such as a wiredtelephone 54 or wireless telephone 56. Essentially, the gaming machine20 acts as a telecommunication device, in similar fashion to a normaltelephone, permitting calls to be placed to other authorizedtelecommunication devices.

In one embodiment, calls may be placed to only “local” or toll-freelocations. In other embodiments, calls may be placed to certain areas orlocations, and in yet other embodiments, there may be essentially norestrictions upon calls.

In yet another embodiment, the call maybe to a player at another gamingmachine. In this embodiment, a call may be placed from one machine toanother, either directly or via the server 48 or other device. In thisembodiment, the gaming machines 20 do not necessarily need acommunication link “to the outside”, but simply need to be able tocommunicate with one another. In one embodiment, the call may be placedto a randomly selected machine, and in another embodiment, only to amachine at which a player is currently identified as playing.

In a step S202 it is determined if the call is completed. Generally,this involves determining if the call has been answered. In a step S203,if the call is completed, then in a step S204, a bonus event may beinitiated. The bonus event may have several purposes. First, the bonusevent may confirm the call has been answered by a participant, and notan answering machine or the like. Second, the bonus event may be used todetermine criteria for the game.

First, the bonus event may include a requirement that the participantidentify themselves. For example, in the case of a player selected froma player club database, the player may be prompted to enter theirpassword, i.d., or other information which identifies them. Preferably,the information which is requested is information which is stored in thedatabase and can thus be used to confirm the identity of the player. Theplayer may speak, enter via their telephone touch-pad or otherwiseprovide the requested information, which is then checked against that inthe database. If the information does not match, the player may not bepermitted to play.

In a preferred embodiment, any player may play. The bonus eventcomprises the participant making a selection as an answer to a question.For example, the bonus event may comprise asking a multiple-choicequestion having several answers. In one embodiment, no answer is wrong,but the selection of an answer corresponds to a multiplier or otherbonus event value. For example, the player may be asked a question andthen be presented with optional answers A, B, C, or D, or 1, 2, 3, or 4.The player may use their keypad or voice to make a selection of ananswer.

In one embodiment, the bonus question is generated by the gamingmachine, server or the like, and the information is transmitted to theparticipant over the telecommunication link once the call is answered.When the call is answered, the participant may also be played agreeting, such as “you have been selected to participate in thephone-a-friend game and you now have the opportunity to win thousands ofdollars”. In one embodiment, where the player is permitted to select theparticipant, the player may be permitted to identify themselves to theirfriend to entice them to play.

As indicated, in a preferred embodiment, each answer is associated witha bonus event value. In one embodiment, the value is a winning valuemultiplier, such as 2×, 4× or the like.

In a step S204 input is received regarding the participant's numbers. Insimilar fashion to the player's numbers, the participant is preferablypermitted to select a lucky number, such as a five digit number. Ofcourse, the participant number could include more or less digits thanthe player number.

In a step S205, game numbers are generated. Preferably, the game numberscomprise a first number the same size as the player's number, and asecond number the same size as the participant's number. For example, ifthe player and participant numbers comprised five digit numbers, then sodo the game numbers.

If the call is not completed or if the call is completed but theparticipant's identification is not confirmed, the game may continuewithout participation by the third party. In such event, the gamepreferably continues at step S205 as well, except that only one gamenumber is generated corresponding to the player. Alternatively, otherevents may be presented to the player, including events which offer amuch lower or smaller jackpot/winning.

In a step S206, it is determined if the player's number match the gamenumbers, and/or if the participant's numbers match the correspondinggame numbers. For example, the first game number is compared to theplayer's number to see if they match. The second game number is comparedto the participant's number to see if they match.

In a step S207, if neither sets of numbers matched, then the gamepreferably ends.

In a step S208, if either or both of the sets of numbers matched, thenan award may be determined and be awarded. For example, in oneembodiment, if just the player's number matched the corresponding gamenumber, then the player may be awarded a monetary win, such as $1000.00.If only the participant's number matched the corresponding game number,then the participant may be awarded a monetary win, such as $1000.00. Ifboth the player and participant numbers matched the correspondingnumbers, then the player may be awarded a large jackpot award, such as$1,000,000.00, and the participant might not participate in an award.

Of course a variety of awards may be yielded as a result of matchingnumbers. In one embodiment, a player and/or a participant may be awardeda win if some but not all of the digits of their numbers matched thecorresponding game numbers. For example, if the player selected 45897and the game number for the player was 45896, the player might beawarded an award comprising some portion of the top award.

In one embodiment, the award which is paid to the player or participant(other than the jackpot award), may be multiplied by the multipliervalue which was yielded as part of the participant's play (in stepS203). For example, if the participant's numbers matched and themultiplier generated earlier was 2×, then the player might be paid$2000.00 (i.e. 2×$1000.00).

Of course a variety of variations of the game are contemplated.Preferably, the bonus event includes the step of forming, or attemptingto form, a communication link with a third party. However, the exactform of the game which is played in association with that event mayvary. For example, where the third party participant is at anothergaming machine, both gaming machines may immediately go into a bonusmode which presents to both players the opportunity to play a game ofvideo poker against one another, or against the house, in an attempt towin a game. Alternatively, both players may be presented with a slottype game which they play in an attempt to obtain a winning result. Aprimary advantage, regardless of the particular type of game which ispresented/played, is the possibility for, if not the actualparticipation of, the third party with the player in the event. Asdescribed below, this adds a great dimension of excitement to the game.

As one aspect of the bonus event, rules or laws may permit participationof only players of certain ages or in certain geographic locations. Partof the play of the event may require confirmation that the participantis eligible to participate. In the case of participants who are selectedfrom a player club database, as indicated above, the confirmation of theidentity of the participant may be sufficient (and where the eligibilityof the participant to play is confirm at the time they sign up toparticipate). In other embodiments, additional information may beobtained to confirm eligibility.

A secondary bonus event in accordance with the invention will now bedescribed in conjunction with FIG. 6. As indicated above, such a bonusevent may be initiated based upon a player receiving a particular symbolor combination of symbols, as in step S14 of the method of game playillustrated in FIG. 3.

As one example, in the case of the symbol sets described above as usedin the play of the base game, a set of any three “slot-a-thon” symbolson an active payline may initiate this bonus event. Once again, whenthis bonus event is activated, audible and/or visible information ofsuch may be presented to the player to make them aware of the event andto add excitement to the game.

In one embodiment, the bonus event initiates with the generation anddisplay of a game number, as in step S300 of FIG. 6. In one embodiment,the game number is a 7 digit number which is randomly generated. Thegame number is preferably displayed by the gaming machine, such as usingthe video display 38 thereof. In one embodiment, the number is displayedas the result of the simulated spin of seven (7) video reels each havinga single position. In one embodiment, the “spinning” of the video reelsis initiated by the player, such as by the player using the “spin”button 28 of the gaming machine.

In a step S301 it is determined if the generated number is apredetermined number, such as 777-7777. If not, then the bonus eventcontinues in a step S304, the game number is utilized to create a bonusamount. In one embodiment, the digits of the number are added to createa value. For example, the game number 555-1212=21. This value would beassigned as a bonus value in the bonus event. In one embodiment, thebonus value is posted to the player, such as by display on the videodisplay or other display of the gaming machine.

In a step S303, the player is preferably provided the opportunity toincrease the size of the bonus value. In one embodiment, the playerplays for a multiplier value.

In one embodiment, the event is configured as a telephone call. Variousevents may be utilized to determine the multiplier value, such as anumber of rings (in similar fashion to that described above), or theplayer might place a call to third party (either via a number of theirchoice or a pre-selected number, as described above) and the third partymight answer a question having answers with associated multipliervalues, or a call might be initiated to a player of another gamingmachine who then engages in an event, such as the selection of a numberor other event. Multiplier values might be displayed by the gamingmachine and the player might utilize the telephone to stop a pointer orthe like upon a particular value (such as by the player lifting thehandset, dialing a number or the like). Of course, other events might beutilized to determine the multiplier value. It is preferred, however,that the event be a telecommunication-related event, as thatsubstantially increases the excitement of the game.

Based upon the outcome of the event, the multiplier value is determined.In a step S304 the total bonus event award is determined. For example,if the player's starting bonus value was 21 and they obtained amultiplier value of 5×, the player would win 105 credits/coins or othervalue. That winning would preferably be awarded to the player, such asin the form of credits at the gaming machine. In a step S305, the gamethen ends.

In step S301 if it was determined that the game number comprised thespecial or particular number, then a different event is preferablypresented to the player. In one embodiment, the player is provided theopportunity to play a special game for the opportunity for winnings.Preferably, the player is allowed to play the game with no additionalwager necessary.

In one embodiment, in a step S306, a game play time is initiated. In oneembodiment, the game play time may be fixed. In other embodiments it maybe randomly selected or determined through some secondary event.Preferably, the total time of the event and the time remaining in theevent are displayed to the player, as in step S307. In the case of anembodiment of a gaming machine, such as illustrated in FIG. 1, thegaming machine 20 may include a timer 60. The timer 60 may be a digitaldisplay, mechanical timer or the like. As illustrated, the timer islocated in a top box portion of the gaming machine, but is could belocated elsewhere. In addition, the time information could simply bedisplayed on another display (such as display 38) of the gaming machine.

Preferably, the event starts at a step S308, with the timer displayingremaining time as the time of the event expires. In one embodiment, theevent is the play of a video slot game presented on a display of thegaming machine, such as display 38 of the gaming machine 20 illustratedin FIG. 1.

For example, the game may comprise a five (5) reel, nine (9) paylinevideo slot machine which traditional symbols. Such games are well knownin the art. Preferably, during the active time period, the player maypress the “spin” button to initiate the game. The outcome of each spinis determined to see if the result was a win or loss. Preferably,certain symbols or combinations thereof when occurring along one of thepaylines, is deemed a winning combination, as is known in the art. Inone embodiment, at least one set of symbols along a payline results inthe award of a jackpot amount, such as $1,000,000.00. For example, oneset of symbols on the reels may comprise “Slot-A-Thon” symbols, and aset of those symbols on all reels along a payline, may trigger thejackpot winning amount.

Game play ends in a step S309 when the time expires. In a step S310, thetotal bonus award is determined and awarded to the player. For example,a player might play 14 games, with 5 of the games yielding winningcombinations with associated winning values of 10, 100, 400, 5 and 20,for a total winning of 535 during the event. After the bonus award ispaid to the player, the game ends in step S310.

Of course, the invention may have various forms and configurations. Thebase game of the invention may have a variety of other forms than asdescribed above. The base game could comprise a video slot game, andcould even comprise other games such as video poker, electronic bingo orthe like.

The game of the invention need not include all of the game playvariations described. For example, the game may only include the basegame and one of the bonus events, such as either a free spin bonus orparticipant bonus.

In one embodiment, the bonus events of the invention may be configuredas stand-alone games or base games themselves having bonus events. Forexample, the participant bonus could itself comprise a base game. In onesuch configuration, a player might be required to place a wager, andwould then be allowed to input their player numbers and attempt to calla participant.

The games of the invention may be presented at a variety of gamingmachines or systems other than that described in conjunction with FIGS.1 and 2. For example, the games could be presented in a mobile gamingenvironment, such as on cellular phones. For example, a player mightutilize their cellular phone to communicate with a game server. In theevent a base game is a winning event triggering a participant bonus, theserver or player might be permitted to call another participant (forexample, the server might place the call and link the player andparticipant in “conference” call type fashion).

In another embodiment, the games of the invention may be implemented inan on-line format, such as from home or work computers. Once again, theplayer may connect to a server gaming device, such as over the Internet.Game play may then proceed as described.

In these latter embodiments, it will be appreciated that software orgame code may be required to be installed or loaded onto the device toenable play of the game. Such software may be downloaded to thosedevices or be permanently loaded into a memory thereof when they aremanufactured or the like.

In one embodiment, the games of the invention may be played as “skill”games. For example, a player may or may not be required to place awager. The player may then play for points. A player obtaining certainnumbers of points (or a participant who does so via the participantportion of the game) may be entitled to prizes, such as giftcertificates and goods. Such a variation of the game has particularapplicability to on-line and wireless environment presentations.

As indicated, the gaming machine or other device which is utilized topresent the game is or includes a telecommunication device. As describedabove, in one embodiment a gaming machine may incorporate such a device.The device may include a handset, speaker-phone, headset or other devicefor transmitting audible information to the player and permitting theplayer to answer and/or initiate calls. Of course a wide variety ofother devices may be utilized. A gaming machine might include a wirelessor “hand-held” phone unit, rather than a wired handset. In oneembodiment, as indicated, the telecommunication device may be entirely“internal” to the machine. The image of a telephone or the like may bedisplayed when a call is to be placed or is incoming and needs to beanswered. The player may utilize buttons or other inputs to answer andplace calls.

As also indicate, the gaming machine or other device via which the gameis presented may vary. As indicated, the machine may have a traditional“gaming machine” style or configuration. The various methods, includingthe games, may be presented in other environments, such as in adistributed environment. For example, the games may be implemented as“Internet” games. In one embodiment, a player may contact a game host,such as via computer via a communication link such as the Internet.

In one embodiment communication with the third party participant maytake other forms. For example, in an “Internet” or similar environment,calls may be effected via the Internet, such as by a standardtelecommunication-type call to a telephone or another party's computer,and by other means, such as an Instant Messenger™ message, email messageor the like, by which a third party may participate.

In one embodiment, various aspects of the invention maybe implemented asan additional system or device to an existing gaming machine. Forexample, a gaming machine may be configured to present a main or basegame. A communication device may be associated with the gaming machine,but not be directly integrated therewith. For example, a communicationdevice may include a display, handset or the like which is physicallyassociated with (connected or mounted thereto, or located proximate themachine), that device forming a part of a “bonus system,” such as bybeing connected to a bonus server which communicates with the gamingmachine. In this configuration, a bonus “system” is essentiallyassociated with a generally separate gaming system including gamingmachines.

It will be appreciated that the odds of obtaining winning combinationsof the main or base game, the odds of triggering a bonus event, the oddsor winning a bonus event, and the payouts, may vary. In one embodiment,the wager or bet which is placed is used to fund payouts for allportions of the game. Thus, the total payout for the base game may berelatively low, in order to fund large jackpots for the bonus/secondaryevents.

In one embodiment, participation in the bonus events, or at least theopportunity to win jackpots, maybe tied to the player's placing a largeor maximum bet. In one embodiment, the largest jackpots or awards may beconfigured as progressive awards. In such an arrangement, the size ofthe jackpot grows (based on bets placed at one or more machines) betweenperiods when it is won. The jackpot may have a minimum funding amount,or may drop to zero when won.

The game could involve the play of more than one participant. Forexample, the game could be configured so that more than one third partyparticipant is called and may participate in the game. In anotherembodiment, multiple opportunities may be provided to form a call with aparticipant. For example, if a player enters their friends phone numberand the call is not answered, the player may be provided one or moreadditional opportunities to place additional calls, or the gamingmachine may similarly be configured to attempt to complete such a call.

It will be appreciated that the methods of the invention are exemplaryand the various steps may be changed, including their order. Forexample, instead of determining the results of a set of games in a freespin bonus, the result of each game are essentially determined or knownat the end of each game. Further, various of the features of the variousbonus events may apply to one another or be incorporated therein, or beincorporated in entirely different games.

The gaming machine, system and games of the invention have a number ofadvantages.

One aspect of the invention is a game, and more particularly a wageringtype gaming offering the chance for monetary winnings, which has theopportunity to involve a participant. This aspect of the game addssignificant excitement to the game. First, the player may be offered theopportunity to select their “friend” to play the game, buildingcomradery and the like. Second, the player does not known if the callwill be completed. If completed, the player and participant engage in abonus event providing them an opportunity for significant winnings.

Another aspect of the game is a game which includes telephone ortelecommunication calls to or from the player. The use of a telephone ortelecommunication link adds excitement and a new dimension to game play,which traditionally relies upon simple viewing of the gaming machineitself. In the games of the invention, the player must interact with thegaming machine to place and/or answer the telephone/calls.

As indicated, in one embodiment, the possible participant in the bonusgame may be selected from a player club database. One aspect of theinvention is thus a system including a database of player informationincluding player telephone numbers. In one embodiment, the database mayinclude additional information such as player identification informationfor player verification purposes. As part of the system, players whosign up for the club are randomly selected (or their telephone numbersare), entitling them a chance to participate in the game.

In this regard, players are enticed to sign up for the player club forthe opportunity to participate in the game. As is known, casinos andother entities find very valuable the ability to identify and trackplayers, as such is a marketing tool which they can utilize to attractand keep players. In accordance with the invention, a valuable means isprovided to entice players to sign up for the club.

In an embodiment where the game involves calling a player of anothergaming machine, participation in the club/tracking system may be furtherenhanced where only players who are “logged in” may be identified aspotential participants in the game.

Another embodiment of the invention is a game which offers a pluralityof different bonus or secondary events. Because of the variety of bonusevents, the play of the game is not repetitive, and instead remainsexciting to the player.

Various of the features of the invention have been described as “bonusevents.” The events are referred to as a “bonus event” primarily becausethey offer play and/or a win opportunity which differs from the basegame or event itself. However, the bonus events may be considered in oneor more embodiments as essentially being a part of the base event, butjust comprising one of the potential variations of game play of the basegame or event, rather than events separate therefrom, since in apreferred embodiment the bonus events are triggered by outcomes of theplay of the bonus event.

Another aspect of the invention is an event, and preferably a bonus gameor event, which has occurs or is enabled for play during a particulartime interval. As indicated, a bonus event may be initiated at a starttime and end after a period of time. The duration of the bonus eventmight be fixed, or might vary, such as randomly or based upon variouscriteria, such as the result of the main game which triggered the bonusevent, the player's wager or the like. In one embodiment, a timer isassociated with the event for displaying remaining play time.

Another aspect of the game is that, even aside from the participantbonus, the game (including bonus or second events), offer a great dealof player participation. For example, compared to a simple wheel spin asa bonus event, the bonus events of the invention involve answeringcalls, making decisions regarding when to answer calls, playing gamesduring time periods, and making number selections.

One aspect of the invention is the ability to involve a participantregardless of their location. The game offers the ability of aparticipant to play via a cellular phone, land line or othertelecommunication link (including computer telecommunication link, suchas the Internet), essentially enabling them to be anywhere toparticipate in the game.

It will be understood that the above described arrangements of apparatusand the method there from are merely illustrative of applications of theprinciples of this invention and many other embodiments andmodifications may be made without departing from the spirit and scope ofthe invention as defined in the claims.
